Paper Abstract

A study is presented to investigate a magnetostrictive flow sensor for use in a scour monitoring system. Using a thin Galfenol “whisker” a sensor is constructed to detect the presence of water flow. Due to the desire for the whisker to respond dynamically rather than with just a quasi-static deflection when in a steady stream of flowing water, two configurations of the sensor are tested, one in which only the bare whisker is exposed to the water flow and one in which an unstable airfoil is fixed to the whisker. Three primary conclusions are inferred. First, the study confirms that Galfenol has the structural properties necessary to create a tactile sensor. Second it has been demonstrated that this tactile sensor is capable of being sensitive to water flow. Finally, it has been determined that alterations to the geometry of the whisker, specifically the addition of an unstable airfoil, can create the necessary dynamic response required for such a sensor.
